• a(n+1) is the smallest square > a(n) such that the digits of a(n) are all (with multiplicity) properly contained in the digits of a(n+1), with a(0)=4.at n=6A067714
• a(n+1) is the smallest square > a(n) such that the digits of a(n) are all (with multiplicity) contained in the digits of a(n+1), with a(0)=4.at n=7A067717
• Define sds(n) = sum of the squares of the digits of n. Sequence gives smaller of two consecutive squares with sds(k^2) = sds((k+1)^2).at n=20A069645
