Fermat's Last Theorem has been proved on the basis of school Physics, Mathematics, analytical Geometry. The main conceptions of the proof one can write on a math toy in the form of a wooden cube for children. Six faces of the cube are enough to deliver the main ideas of proof.

Summary: between the general stratigraphic scale of a phanerozoic eonothem and the general geochronologic scale there is one-to-one correspondence (bijection). For demonstration of bijection the piece of a stratigraphic scale, to the corresponding Phanerozoic is chosen. Expansion of a scale to the Archean inclusive is possible. Bijective scales are united in a geocontinuum which forms with Cambrian, Ordovician, Silurian, Devonian, etc. The scale of a new type is made by association of three scales: stratigraphic, geochronologic, geocontinuum scales. The scale of new type possesses wider didactic, etc. opportunities.

Summary: between the general stratigraphy scale of the Permian system and the general geochronologic scale of the Permian there is one-to-one correspondence (so-called "bijection" by the theory of the Cantor). Couples of such divisions are considered: System – Period, Series – Epoch, Stage – Age. For demonstration of bijections the piece of the International Chronostratigraphic Chart corresponding to the Perm system is chosen. Divisions which volume and content are proved by a biostratigraphic method treat the straton possessing property of bijection. The Permian system, its departments, tiers treat such divisions.
