Presentation

minimal degree	μ(G) = 28
transitive degree	μ_t(G) = 128

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

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