Velocity Create Command

Following is the input script .I cannot understand velocity create command in this. what is 102486 mean in this.

units
real
atom_style
full
boundary
p p p
variable
temp equal 86.5
read_data
argon_864.data
pair_style
lj/smooth 10.0 12.0
pair_coeff

timestep 5.0
velocity all create ${temp} 102486 mom yes rot yes dist gaussian
fix NVE all nve
thermo 1
thermo_style custom step temp press etotal ke pe
run 1000
write_data
argon_864_run1.data
write_restart argon_864_run1.restart

That is a random number seed (https://en.wikipedia.org/wiki/Random_seed) for generating random numbers, which are used to create random velocities on atoms.
