The automata starts with 2 entries on each axis of value 3.
Defined value(u,v) for any u,v natural the value of each cell of the automata.
The axis(u,0),(u,-1) and (0,v),(-1,v) are value 3.
Matrix (with entries):

FORMULA
value(v,u)= (In order of priority)
if( (v,u-1)+(v-1,u)+(v-1,u-1)+(v,u-2)+(v-2,u)-(v-1,u-2)-(v-2,u-1) )>10;0
if( (v,u-1)+(v-1,u)+(v-1,u-1)-(v,u-2)-(v-2,u) )=5;3
if( (v,u-1)+(v-1,u)+(v-1,u-1)+(v-1,u-2)+(v-2,u-1)-(v-2,u-2) )=3;2
if( (v-1,u-2)+(v-2,u-1)+(v-2,u-2)+(v-1,u-1)-(v,u-1)-(v-1,u) )=1;1
if nothing= floor(((v,u-1)+(v-1,u)+(v-1,u-1)+(v,u-2)+(v-2,u)-(v-1,u-2)-(v-2,u-1))/7 +1)
EXAMPLE
value(1,1) = floor(((3)+(3)+(3)+(3)+(3)+(3)+(3))/7 +1) = 4,
value(1,2) = floor(((4)+(3)+(3)+(3)+(3)+(3)+(3))/7 +1) = 4,
value(2,1) = floor(((3)+(4)+(3)+(3)+(3)+(3)+(3))/7 +1) = 4,
