Here, 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).
