Abstract

For each finite primitive subgroup GG of PGL4(C)\operatorname{PGL}_4(\mathbb{C}), we find all the smooth GG-invariant quartic surfaces. We also find all the faithful representations in PGL4(C)\operatorname{PGL}_4(\mathbb{C}) of the smooth quartic GG-invariant surfaces by the groups: A5,S5,PSL2(F7),A6,Z24Z5\mathfrak{A}_5,\mathfrak{S}_5, \operatorname{PSL_2(\mathbb{F}_7)},\mathfrak{A}_6,\mathbb{Z}_2^4\rtimes\mathbb{Z}_5 and Z24D10\mathbb{Z}_2^4\rtimes D_{10}. The primitive representation of these groups are precisely the subgroups of PGL4(C)\operatorname{PGL}_4(\mathbb{C}) for which P3\mathbb{P}^3 is not GG-super rigid. As a byproduct, we show that the smooth quartic surface with the biggest group of projective automorphism is given by {x04+x14+x24+x34+12x0x1x2x3=0}\{ x_0^4 + x_1^4 + x_2^4 + x_3^4 + 12 x_0 x_1 x_2 x_3= 0\} (unique up to projective equivalence).
