Dear seqfans,

As it may become clear from the examples given in A293701, normally a(n)<n, but for some specific values of n, like 1 and  3, a(n)=n, meaning that the whole sequence of first differences A293700 from 1 to n is a palindrome. These specific values of n make up, themselves, an interesting sequence starting 1, 3, 5, 7, 9, 11, 13, 15, 17, 46, 83, 120, 157, 194, 231, 268, 305, 342, 379, 416, 453, 490, 527, 564, 601, 638, 675, 712, 749, 786, 823, 860, 897, 934, 971, 1008, 1045, 1082, 1119, 1156, 9105, 19792, 51817, 83842, 201253, 318664, 436075, 553486, … I wonder would this sequence deserve being published with its own number although it is just a subsequence of A293701.
