Comments

This way of representing the block structure of A104324 is used by Zhang et al. (2017), but of course only makes sense for blocks 0 through 9.

Examples

			The initial blocks are as follows:
 0,
 1,
 22,
 323,
 42344,
 52344545,
 6234454564566,
 723445456456674566767,
 8234454564566745667678456676786788,
 9234454564566745667678456676786788945667678678896788989,
 ...
but if the commas are inserted (as they should be) then we see the blocks more clearly:
 0,
 1,
 2,2,
 3,2,3,
 4,2,3,4,4,
 5,2,3,4,4,5,4,5,
 6,2,3,4,4,5,4,5,6,4,5,6,6,
 7,2,3,4,4,5,4,5,6,4,5,6,6,7,4,5,6,6,7,6,7,
 8,2,3,4,4,5,4,5,6,4,5,6,6,7,4,5,6,6,7,6,7,8,4,5,6,6,7,6,7,8,6,7,8,8,
 9,2,3,4,4,5,4,5,6,4,5,6,6,7,4,5,6,6,7,6,7,8,4,5,6,6,7,6,7,8,6,7,8,8,9,4,5,6,6,7,6,7,8,6,7,8,8,9,6,7,8,8,9,8,9,
 10,2,3,4,4,5,4,5,6,4,5,6,6,7,4,5,6,6,7,6,7,8,4,5,6,6,7,6,7,8,6,7,8,8,9,4,5,6,6,7,6,7,8,6,7,8,8,9,6,7,8,8,9,8,9,10,4,5,6,6,7,6,7,8,6,7,8,8,9,6,7,8,8,9,8,9,10,6,7,8,8,9,8,9,10,8,9,10,10,
