Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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