  Interacting Self Avoiding Walk (ISAW) on a lattice is a simple model to study
the Coil to Globule transition of linear homopolymers. The temperature at which
the transition takes place is called the theta temperature. The value of theta
temperature depends on the chosen lattices. The value of theta temperature for
ISAW on FCC lattice is reported as $6.46$ in a simulation study [J. Chem. Phys.
{\bf 135}, 204903 (2011)]. Latter it has been reported as $7.614$ [J. Chem.
Phys. {\bf 138}, 024902 (2013)]. Simulations in these two studies involved long
chains with over 2000 monomers. In this paper, we present a method that gives a
reliable estimate of the theta temperature of ISAW on FCC lattice using chains
of shorter walk lengths (less than 100 monomers). We compute density states of
ISAW on FCC lattice by employing growth walk algorithm and then we use the
recently introduced pseudo order parameter method to estimate the theta
temperature. The value obtained from our method agrees very well with latter
reported result of $7.614$. In order to corroborate our result we also estimate
the theta temperature using the celebrated partition function zeroes method.
