Presentation

minimal degreeμ(G) = 21
transitive degreeμt(G) = 80

A minimal faithful permutation representation — 3 generators on 21 points:

(2,3)(4,5)(7,12,11,8)(10,13)(15,16,19,20)(18,21);(1,2,4,5,3)(7,8,10)(11,12,13)(15,16,18)(19,20,21);(6,7)(8,10)(9,11)(12,13)(14,15)(16,18)(17,19)(20,21)

Polycyclic presentation:

2,3,5,2^8|b^a=b^2,c^a=c^4,d^a=e,d^b=e,e^a=d,e^b=de,f^a=g,f^b=g,f^e=fk,g^a=f,g^b=fg,g^d=gk,h^a=i,h^b=i,h^e=hj,i^a=h,i^b=hi,i^d=ij
