Algorithm3 packs the sieve more tightly than regular odds-only (ie. in wheel6 formation, 2 bits per 6 numbers). Other than that, it's pretty much straight-up Eratosthenes. The clever flip-flops (k = 3 - k and ij = t - ij) disappear when the loops are unrolled (by hand or by compiler).

All in all, I don't expect this algorithm to hold much interest.
