[seqfan] Re: The last digit "d" of a(n) is present in a(n+1+d) --END

[zak seidov]

Writing only n (not squares), the sequence's start and end are:

{0,1,2,3,4,5,6,7,9,8,10,15,12,16,20,11,22,13,18,14,28,19,17,..
...,954,1838,1003,1865,1030,1935,1054,2082,1034,2878,1037}
1202 terms! Seq is finite(()
