• a(n) is smallest number >= a(n-1) such that a(n) plus any set of the previous values of the sequence is a nonsquare; starting with a(1) = 2.at n=29A064776
• a(n) is smallest number >= a(n-1) such that a(n) plus any set of the previous values of the sequence is a nonsquare; starting with a(1) = 2.at n=30A064776
• a(n) is smallest number >= a(n-1) such that a(n) plus any set of the previous values of the sequence is a nonsquare; starting with a(1) = 2.at n=31A064776
• a(1)=1 and for n>1, a(n) is the smallest multiple of a(n-1) which has no nonzero digit in common with a(n-1).at n=17A079838
