• Smallest nontrivial extension of n-th palindromic prime which is a prime.at n=36A030680
• Start with a single square; at n-th generation add a square at each expandable vertex (this is the "vertex to side" version); a(n) is the sum of all label values at n-th generation. (See comment for construction rules.)at n=25A247903
