cp's OEIS Frontend

This is a front-end for the Online Encyclopedia of Integer Sequences, made by Christian Perfect. The idea is to provide OEIS entries in non-ancient HTML, and then to think about how they're presented visually. The source code is on GitHub.

A364927 List of free polyplets in binary code (as defined in A246521), ordered first by number of bits, then by value of the binary code.

Can be read as an irregular triangle, whose n-th row contains A030222(n) terms.

Examples

			As irregular triangle:
  1;
  3,  6;
  7, 11, 14, 25, 56;
  ...
The A030222(3) = 5 3-polyplets are oriented as follows to obtain their binary codes (see A246521):
  . . .   . . .   . . .   . . .   5 . .
  2 . .   . . .   2 . .   . 4 .   . 4 .
  0 1 .   0 1 3   . 1 3   0 . 3   . . 3
This gives the binary codes 2^0+2^1+2^2 = 7, 2^0+2^1+2^3 = 11, 2^1+2^2+2^3 = 14, 2^0+2^3+2^4 = 25, and 2^3+2^4+2^5 = 56, respectively.
