Presentation

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

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

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