Presentation

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

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

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