specifically, the 11th discrete Semiprime, it being the 7th of the form (2.q). the first member of the third cluster of two discrete semiprimes 38, 39 the next such cluster is 57, 58. with an aliquot sum of 22 in an aliquot sequence of five composite numbers (38,22,14,10,8,7,1,0) to the Prime in the 7-aliquot tree. 38 is the first semiprime within a chain of 4 semiprimes in its aliquot sequence (38,22,14,10). The next semiprime with a four semiprime chain is 166.
