• Ultra-useful primes: smallest k such that 2^(2^n) - k is prime.at n=14A058220
• Least K such that K*p(n)#-1 is the first of twin primes and 2*(K*p(n)#-1)+1 is prime, so K*p(n)#-1 is the first of twin primes and a Sophie Germain prime.at n=44A117848
• Number of (w,x,y,z) with all terms in {0,...,n} and w=max{w,x,y,z}-2*min{w,x,y,z}.at n=24A212745
• Smallest k such that 4^(4^n) - k is prime.at n=7A364452
• Number of ASCII letter 'A' bytes that when compressed with zlib generate a new record longest compressed byte stream.at n=40A375585
