Presentation

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

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

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