[seqfan] An infinite seq. in same spirit as Eric's "1862"

[Neil Sloane]

Peter Kagey, Rémy Sigrist, and I have been studying A327460:

Lexicographically earliest infinite sequence of distinct positive integers
such that for every k >= 1, all the k(k+1)/2 numbers in the triangle of
differences of the first k terms are distinct.

1, 3, 9, 5, 12, 10, 23, 8, 22, 17, 42, 16, 43, 20, 38, 26, 45, 32, 65, 28,
64, ...

I hope Peter and Rémy will agree if I say that we do not yet fully
understand it!
