Presentation

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

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

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