A110095: non prime first differences

[Alexandre Wajnberg]

Hi,

A110095 is "least non-prime sequence whose first differences are 
non-prime".
I'm submitting the sequence of these first differences:

1 8 1 4 1 1 4 1 1 4 1 1 4 1 1 1 1 4 4 1 1 4 1 1 4 1 1 4 1 1 1 1 4 4 1 1 
1 1 4 4 1 1 4 1 1 1 1 4 4.

Only 1's and 4's (except the "8" at the beginning).

The 4's are obviously related to the prime numbers, they correspond to 
any isolated prime (the second prime of twins allways "masked");
and the 44's relate to some cousin primes (not all).

This seq (this little handmade part!) seems to be reducible to 
concatenated substrings
a == 1 1 4  and
b == 1 1 1 1 4 4 :

(1 8 1 4) a a a b a a a b b a b...

I wonder
-if it's very the case (may be are there further other substrings of 
1's and 4's);
-if there are super patterns in there, or possible regroupings of 
aaab's and bab's?

Could someone check "longer-term"?

Thanks

Alexandre

PS: aaab's and bab's and shoo ba beloobah (ooops! sorry)
