Presentation

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

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

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