Claim. Theorem 3 of the paper states "" as . The paper's (Section 3) is the largest such that the edges of can be colored with colors with no monochromatic copy of , one less than the problem's least forcing order, which leaves the asymptotic formula unchanged. The upper bound comes from the paper's inequality (7), , with Füredi's bound on the Turán number of ; the lower bound comes from an almost complete coloring whose color classes are copies of the projective norm-graph , each free of , with the uncolored edges colored recursively. The abstract presents the result as settling a problem of Chung and Graham, who with Spencer had shown . The theorem is paged at Theorem 3 of the library's source card, whose locators are those of the authors' ten-page manuscript (Theorem 3 on p. 6). The zbMATH review Zbl 0935.05054 states the same result.
Covers. The instance of Problem 558, under the problem page's reading that an asymptotic formula in for fixed and determines the instance. Not covered: every other pair , and the paper's Theorem 8, which gives only the order for fixed and , without constants.
Dating. The page is dated by the issue month of the journal record (J. Combin. Theory Ser. B 76 (1999), no. 2, July 1999, per the Crossref record); the day in the page name is a placeholder.
Acceptance. Refereed: Norm-graphs: variations and applications,
J. Combin. Theory Ser. B 76 (1999), no. 2, 280--290. The site's curator,
T. F. Bloom, credits the asymptotic to this paper in the problem's
commentary, on a page labeled OPEN (last edited 8 February 2026, accessed
2026-09-17); that label does not mark the problem or this part settled, so
the credit is recorded here and is not reviewed evidence.
Read depth. Claims checked: Theorem 3, the Section 3 definition and inequality (7) were read in the author manuscript; the proof was read for its structure and is not checked, and nothing is independently reviewed in this corpus. The journal text is not compared with the manuscript.
Depends on. Nothing in this wiki; the result is the paper's own theorem.
