Presentation

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

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

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