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