Presentation

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

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

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