Other things (possibly stranger)

• OEIS A335992 and A335993: natural numbers that are the average of more pairs of distinct twin primes than any previous natural number.
• The Wandering Mathematician was my math blog in high school. I’m still proud of it.
• I wrote an article on Riemann’s Rearrangement Theorem for Chalkdust and a set of problems for Girls’ Angle meant as a gentle introduction to infinite numbers.
• My high school required all students to write a piece of original research over their junior summer. This, starring the Look and Say Sequence, was mine.
