Presentation

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

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

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