Proof step 5 from proof fermat-2 (previous step)

gcd(j, i) = 1, prime(j), ≡mod(i * i0, 1, j) ⊦ ≡mod(i ^ (j - 1), 1, j)

User applied rule cut formula

And obtained the following new goals

Proof step 6:
≡mod(i0 * i * i ^ (j - 1), 1, j), gcd(j, i) = 1, prime(j), ≡mod(i * i0, 1, j) ⊦ ≡mod(i ^ (j - 1), 1, j)
Proof step 10:
gcd(j, i) = 1, prime(j), ≡mod(i * i0, 1, j) ⊦ ≡mod(i0 * i * i ^ (j - 1), 1, j), ≡mod(i ^ (j - 1), 1, j)

Rule argument

fma: ≡mod(i0 * i * i ^ (j - 1), 1, j)

Additional information

Used formulas: ≡mod(i0 * i * i ^ (j - 1), 1, j)
