Presentation

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

A minimal faithful permutation representation — 5 generators on 28 points:

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