Seems to be another round of declaring ourselves elsewhere. I’m mostly not here, mainly hanging out at Finite Group https://t.co/ffi0bjOCPo - join the chat community for free. Otherwise, I’m @peterrowlett@mathstodon.xyz @peterrowlett.bsky.social @peterrowlett@threads.net

Social media is still in a mess. Here’s my current position: https://t.co/nqz7oVDzZM

Had a lovely day today — we ran an outreach event for year 12s from around Sheffield for Maths Week England - mathematical modelling, puzzles, problem solving, and lots of applications and careers maths leads to. #mwe24

.@Ayliean has taken the opportunity to mention the new Can Humans Say The Largest Prime Number Before We Find The Next One project, details of which are at

@peterrowlett @stecks and overlapping an emirp and its reversal (e.g. 131, which is 13 and 31). He wrote some code and found all the primemirps under ten million! Check out this blog post: https://t.co/KVyESB3SZe The primemirps Peter found are now in OEIS: https://t.co/McSYPkXYRF 2/7

We start our penultimate session of the day with @PeterRowlett, who heard @stecks talk about primes in a https://t.co/6gBtlbHCua livestream, which got him playing with emirps - primes which are still prime with the digits reversed, and primemirps - obtained by concatenating 1/7

.@stecks and I stare deep into an area the size of Wales and draw mathematical inspiration from the experience. And have some fun with silly units. https://t.co/pV1lvuV95f

I wrote about queuing in this weekend’s @newscientist! And I wrote this week’s puzzle exploring a technique involving multiplying a number’s digits together.

For free, you can now sign up at https://t.co/6sorj0nMPE to join us in a fun, friendly maths community. You can also pay to access monthly livestreams either as a subscription or pay-per-view, and other benefits.

You may have seen me going on about being in the Finite Group - a Discord with monthly livestreams of fun people (@peterrowlett @ayliean @mscroggs) talking about maths - and now joining the Discord is now free! Join here to find out more:

What is maths? Who is it for? Where can it lead you? We offer more diverse answers to these questions than students might expect in this sixth form event for Maths Week England @maths_week. If you're local to Sheffield & teach A Level maths check it out! https://t.co/enr1qc79vP

This week's Finite Group livestream highlight is me responding in shock when @stecks does some error correction. Join at https://t.co/Rqssw7sxQp if you want to be there the next time something this exciting happens.

I talked about the mathematics of ballots on the @MathsObjects podcast with @KatieSteckles and @peterrowlett and it was so much fun! https://t.co/QytheA1XfA

We chat election mathematics on today’s new Mathematical Objects podcast with special guest @Samuel_Hansen.

See @mscroggs generalising the folding of a zine in this Finite Group highlight. https://t.co/6sorj0okFc

Read nine articles published during the 60 year history of the Institute of Mathematics and its Applications, each with a new introduction. Includes Lighthill on animal flight, Ollerenshaw on Rubik's Cube & Wilkinson on numerical error. https://t.co/oEd2UBcVOH

A Finite Group livestream highlight - @Ayliean has translated some fundamental theorems into emoji for @stecks to guess. Don’t miss out on the October livestream - join the group at https://t.co/6sorj0nMPE

Today's new Mathematical Objects podcast has @stecks telling me about space-filling curves!

Enjoying listening to @stecks talk about David Singmaster’s work on the Rubik’s cube at this @mathshistory meeting on recreational mathematics. Slide is a page from his seminal ‘Notes on Rubik’s Magic Cube’.

Little highlight from a Finite Group livestream. We do these monthly. To come along, join the Finite Group at https://t.co/6sorj0nMPE
