Later it was also produced by compression of fullerene and it was confirmed that it is the hardest and least compressible known material, with an isothermal bulk modulus of 491 gigapascals ( GPa ), while a conventional diamond has a modulus of 442 – 446 GPa ; these results were inferred from X-ray diffraction data, which also indicated that ADNRs are 0. 3 % denser than regular diamond.

This gives a large number of separate problems ; for example, the original proofs of existence and uniqueness of the monster totaled about 200 pages, and the identification of the Ree groups by Thompson and Bombieri was one of the hardest parts of the classification.

The complexity class P is contained in NP, but NP contains many important problems, the hardest of which are called NP-complete problems, for which no polynomial-time algorithms are known for solving them ( although they can be verified in polynomial time ).

The hardest problems in PSPACE are the PSPACE-Complete problems.

In complexity theory, computational problems that are co-NP-complete are those that are the hardest problems in co-NP, in the sense that they are the ones most likely not to be in P. If there exists a way to solve a co-NP-complete problem quickly, then that algorithm can be used to solve all co-NP problems quickly.

NP-hard ( non-deterministic polynomial-time hard ), in computational complexity theory, is a class of problems that are, informally, " at least as hard as the hardest problems in NP ".

; NP-equivalent: Exactly as difficult as the hardest problems in NP, but not necessarily in NP.
