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