## Statement

For input classes (4A,7A), the PSL(2,7) class-algebra coefficient for output class 7A is 14, and the coefficient for output class 7B is 0.

## Caution

These coefficients neither derive the current leptonic phase nor establish a mechanism relating their value to G2.

## Primary source

Paper 8, §2, PSL(2,7) class-algebra structure constants, PDF p.122: "7A 7B c4A,7A = 14, c4A,7A = 0."
