    For the first mentioned sequences based on fonts, what's the first number in the sequence that has less digits than the previous number?

      It looks like that never occurs for Helvetica (A316600) due to the absence of kerning. However, with Arial (A316599) the description notes:

      > a(29368) = 111111 is a first notable anomaly, because its bounding box width of 2675 lies between those of a(29367) = 49115, with bounding box width 2655, and a(29369) = 70002, with bounding box width 2681.

    The edit history of the “nonsense sequence” makes for painful reading.

      I am missing some context here what was wrong with the original description?

        The original title was this:

        > Graph substitution of two octahedra inside an icosahedron connected at p=1: disconnected at p=0 ( concept similar to two tetrahedra inside a cube).

        Can you explain what that means, and how it leads to a sequence of integers? I think it is nonsense.

    Can somebody explain what "less" keyword means? I'm asking for a friend.

      According to the wiki [0], "This is a less interesting sequence and is less likely to be the one you were looking for."

      Confusingly, "more" means "please add more terms"...
