Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 256

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

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