Terms which would appear in A121737 eight times or more if it included repeats.
There are infinitely many terms in this sequence; see A181746. For example, 548418186007940753739828795801600 = 2^36 * 7980534952482277785600, and additional dimensions may be obtained by replacing 2^36 with n^36 for any positive integer n.

Examples

			With fundamental weights as ordered in Bourbaki, the eight irreducible E6 representations with dimension 7980534952482277785600 have highest weights as follows:
  [ 1, 5, 2, 5, 0, 7]
  [ 7, 5, 0, 5, 2, 1]
  [ 5, 7, 2, 3, 2, 1]
  [ 1, 7, 2, 3, 2, 5]
  [ 1, 5, 6, 1, 0,11]
  [11, 5, 0, 1, 6, 1]
  [ 4, 5, 3, 1, 0,14]
  [14, 5, 0, 1, 3, 4]
