Presentation

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

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

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