I would want to see what the lengths are for other radices.

DIMACS - RUTGERS Experimental Mathematics
Title: Eric Angelini's Comma Sequence
Speaker: Neil Sloane, OEIS Foundation and Rutgers University
Date: Thursday, January 18, 2024, 5:00pm - 6:00pm
Presented via Zoom: https://rutgers.zoom.us/j/94346444480

Abstract:
The Comma Transform of a sequence replaces each comma between the terms by
the number formed by concatenating the single digits to the left and right
of the comma. (E.g., the Comma Transform of the even numbers is 2, 24, 46,
68, 81, 1, ....) The remarkable "comma sequence" is defined by the property
that it starts with 1 and its first differences equal its Comma Transform.
If there is a choice, choose the smallest possibility. It contains exactly
2137453 terms! This talk, based on joint work with Eric Angelini, Michael
Branicky, Giovanni Resta, and David W. Wilson, will analyze this and
related sequences.
