Hi Blue Sky,
I've been putting together a little podcast on Maths History, following The Mathematicians of old.
I'd be honoured if you'd listen along at mathematicians.podbean.com

I am absolutely buzzing following the publication of my very first OEIS sequence.
oeis.org/A389751
Numbers k such that k^3 can be represented as the sum of k consecutive nonprimes.
Eg
a(3) = 9^3 = 76+77+78+80+81+82+84+85+86
Only the first 16 numbers found so far, so please come and add more!

My teacher always told me I wouldn't walk around with a protractor in my pocket, and it turns out she was right.
In other news, I might have discovered a new #OEIS
