Generalized Cullen and Woodall primes can be twins
Generalized Cullen Primes are defined as the primes of the form n.bn+1 with n+2 > b, while generalized Woodall Primes as the form n.bn-1 with n+2 > b. If we loose the restraint of n+2 > b to a plain n > 2, with every b>1, except for n = k^c and mod(n, c)=0，there is a conjuncture
There is always an integer of b>1 that makes n.bn-1and n.bn+1a pair of twin primes.
