Restriction
[edit]Does this article mention anything about polyabolos that are limited to 2 of the 3 diabolos inside them?? The 3 kinds of diabolos are:
- A square
- A big isosceles triangle
- An oblique parallelogram
This article talks about all polyabolos, but I think it would be nice to talk about the number of n-polyabolos that contain only the first 2 kinds of diabolos anywhere in them. The sequence in the article starts 1, 3, 4, 14... but the sequence of n-polyabolos with this restriction is 1, 2, 2, What comes next?? Georgia guy (talk) 20:39, 2 March 2013 (UTC)
- The sequence begins 1, 2, 2, 6, 8, 22, 42, 112, 252, 650, 1584, 4091, 10369, 26938, 69651, 182116, 476272, 1253067, 3302187, 8733551… (sequence A197465 in the OEIS). —Bkell (talk) 01:02, 3 March 2013 (UTC)
