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