We consider ϕ3 theory in 6 − 2ϵ with F4 global symmetry. The beta function is calculated up to 3 loops, and a stable unitary IR fixed point is observed. The anomalous dimensions of operators quadratic or cubic in ϕ are also computed. We then employ conformal bootstrap technique to study the fixed point predicted from the perturbative approach. For each putative scaling dimension of ϕ (Δϕ), we obtain the corresponding upper bound on the scaling dimension of the second lowest scalar primary in the 26 representation (Δ262nd) which appears in the OPE of ϕ × ϕ. In D = 5.95, we observe a sharp peak on the upper bound curve located at Δϕ equal to the value predicted by the 3-loop computation. In D = 5, we observe a weak kink on the upper bound curve at (Δϕ, Δ262nd) = (1.6, 4).
