    Sexy primes are pairs of primes of the form (p, p+6), so-named since “sex” is the Latin word for “six.”  A sexy prime triplet is thus thre primes of the form (p, p+6,p+12)
    The primes in the triplet I found have 5132 digits with
    p=(84055657369* 205881*4001# * (205881 * 4001# + 1) + 210)*(205881 *4001# – 1)/35 + 1
    The complex structure is to ensure that each member of the triplet can be proven prime using the BLS (Brillhart, Lehmer and Selfridge) test. A BLS test on a number of this size takes only about 1 minute.
    Wheras proving a random number of this length prime  would have required months of processing on the PCs available to me.
    Cheers
    Ken
