• Squares whose sum of digits as well as product of digits is a nonzero square.at n=16A061267
• Smallest square obtained by inserting one or more digits between every pair of consecutive digits of n^2.at n=25A080438
• Positive integers n such that if n is a square, then so is r(n), where r(n) is the nonnegative integer defined by cyclic replacement of the digits d of n in base 12, that is, d->d+1 if d<11 and d->0 if d=11.at n=2A127856
