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