OpenAI reports Foulkes’ conjecture for the sixth symmetric power

For every integer b≥6 and finite-dimensional complex vector space V, there is a GL(V)-equivariant injection Sym⁶(Symᵇ V)→Symᵇ(Sym⁶ V).

Sources for this record

What was already known

Foulkes’ conjecture had been proved for smaller fixed symmetric-power indices, and stabilization arguments covered sufficiently large b in cases beyond those indices; the sixth-power full range remained open.

AI involvement AI-led

OpenAI credits itself as manuscript author and states that its internal frontier model produced the results in this release. Individual human input is not detailed enough to establish task-only autonomy.

OpenAI is named as author on the manuscript, and its release attributes the results to an internal frontier model. The individual human input is not detailed enough to establish autonomy.

Importance Notable

Proves the sixth-symmetric-power case for every permitted b and vector-space dimension.

Limitations

The selected claim is for a=6 and b≥6. The linked Lean scope covers the corresponding injection only for b≥30, not the critical range 6≤b<30.

Technical verification Reported

Reported is the default when evidence for a higher level is insufficient. The OpenAI-authored manuscript reports and argues the result, but the reviewed sources do not document a completed check of the full assessed claim.

Human understanding Few

Few is the default when evidence for a higher level is insufficient. No named person is documented as explaining the central argument for this assessed contribution.
