Proof step 24 from proof prime-divides-coef (previous step)

(fac(j) * fac(j + 1)) * i = fac(j * 2 + 1), 0 ≤ j, 0 < j, j + 2 ≤ j0, j0 ≤ j * 2 + 1, prime(j0) ⊦ j0 | (fac(j) * fac(j + 1)) * i, j0 | i

User applied rule insert equation

And obtained the following new goals

Proof step 25:
0 ≤ j, 0 < j, j + 2 ≤ j0, j0 ≤ j * 2 + 1, prime(j0) ⊦ j0 | fac(j * 2 + 1), j0 | i

Rule argument
