%N 6*a(n) is the gap between sexy prime triples in the n-th sexy prime triple triple whose initial term is 5.

%C The nine terms in any sexy prime triple triple {{a, b, c}, {d, e, f}, {g, h, i}} may be arranged to form a 3 X 3 magic square [ h a f / c e g / d i b ].

%e a(3)=246 identifies the third sexy prime triple triple whose initial term is 5: {{5, 11, 17}, {5+6*246, 11+6*246, 17+6*246}, {5+2*6*246, 11+2*6*246, 17+2*6*246}} which is equal to {{5, 11, 17}, {1481, 1487, 1493}, {2957, 2963, 2969}}.
