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