CHAP, xvi]                           FACTORS OP an*b\                                  387
A. Cunningham66 factored 5n 1 for w = 75, 105.
L. Kronecker560 proved that every divisor, prime to t, of (1) is s 1 (mod t) . H. S. Vandiver666 noted that the proof applies to the homogeneous form Ft(a, 6) of (1) if a, b are relatively prime.
D. Bidolle87 gave a defective proof that 3-24l+l is a prime.
