Jonathan Campelli submitted a Comment to Problem 431. Sorting

Aye! The first column is not "sorted according the second column" (only half an explanation). The block of numbers in each row is treated as a fixed unit, and each row is rearranged such that the values in the second column are sorted in ascending order.

Jonathan Campelli submitted a Comment to Problem 659. How long is the longest prime diagonal?

"find the longest diagonal arrangement of primes in spiral(n)" leaves room for misinterpretation. I would have quickly understood: "return the length of the longest diagonal sequence of primes in spiral(n)"
