Inagaki–Tamura shift identity conjecture for partition inequalities

Let p(ncondition)p(n\mid\text{condition}) count partitions of nn satisfying the specified condition. Define

qd(1)(n):=p(nparts1 and differ by at least d)q_d^{(1)}(n):=p(n\mid\text{parts}\geq 1\text{ and differ by at least }d)

and

Qd(1,)(n):=p(nparts±1(modd+3), excluding the part d+2).Q_d^{(1,-)}(n):=p(n\mid\text{parts}\equiv\pm1\pmod{d+3},\text{ excluding the part }d+2).

Inagaki–Tamura shift identity conjecture. If d12d\geq 12 and nd+2n\geq d+2, then

qd(1)(n)Qd4(1,)(n)0.q_d^{(1)}(n)-Q_{d-4}^{(1,-)}(n)\geq 0.

Shift identities of this type can yield information about the modified Alder-type inequalities and improve the bounds in the generalized conjecture. The source gives no resolution of this particular shift identity conjecture.
