Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

A minimal faithful permutation representation — 3 generators on 28 points:

(1,2)(3,4)(5,6,7,10,8,9,11,12)(13,14,16,21,18,22,23,26,17,19,25,27,24,28,15,20);(6,9)(7,11)(14,19)(15,23)(16,25)(22,28);(2,4)(13,15,24,25,17,23,18,16)(14,20,28,27,19,26,22,21)
