A278566 Irregular triangle read by rows: row n gives coefficients when the n-th coefficient of the modular function j (A000521(n)) is written as a linear combination of irreducible characters of the Monster simple group (A001379). 0
1, 1, 1, 1, 1, 2, 2, 1, 1, 3, 3, 1, 2, 1, 4, 5, 3, 2, 1, 1, 1 (list; graph; refs; listen; history; text; internal format)

COMMENTS
The coefficients are given as in Thompson's paper. The choice of coefficients is actually ambiguous because of a linear relation with small coefficients between the terms of A001379 (see Wikipedia). - Andrey Zabolotskiy, Feb 12 2019
