Specialization at T = 169/28 of the rank-16 fibration of X948 given by:
y^2 + (Lx+B)y = x(x+D)(x+E),
where
B = pE + qD + pq(L-p-q),
L = 8164T^2 + 8952744T - 964149,
p = 16016T^2 - 418245T + 5035456,
q = 9722791T - 1496599,
D = 7(1063105316T^4 - 58094740197T^3 + 937133647457T^2 - 618259297572T - 6063714736384),
E = -13(55614319254T^3 - 272746794787T^2 - 717655885809T - 2521269685298).
