Presentation

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

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

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