Table of n, a(n) for n=1..87.

Example

As an irregular triangle, where the first row contains 1 term and row n >= 2 contains A002494(n) terms:
  1;
  1;
  1, 1;
  1, 2, 1, 1, 1, 1, 1;
  1, 2, 1, 1, 1, 1, 1, 1, 2, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1, 1;
  ...
For n = 6, A076184(6) = 12 encodes the graph on 4 vertices and 2 disjoint edges. This graph has 2 components, so a(6) = 2.
