The following probable primes are the starting points of the smallest gigantic pairs of its kind: 10^9999+114862711, smallest gigantic Sophie Germain, 09/09 10^9999+84120327, smallest gigantic CC2 of second kind, 09/09 10^9999+24204297, smallest gigantic Cousin prime (p and p+4), 11/09 10^9999+475341523, smallest gigantic Sexy prime (p and p+6), 10/09 10^9999+2421018649, smallest gigantic Twin, 12/09 10^9999-4374851, largest non-gigantic Twin, 10/09 The largest non-gigantic Twin and smallest gigantic Twin form a quite large twin-prime-gap of 2425393500. All primes were not yet checked for full primality and I guess I will most probably delay this for some years. Regards, Dirk
