Presentation

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

A minimal faithful permutation representation — 4 generators on 28 points:

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