Abstract
Facsimile of a manuscript from the archive of Emanuels Grinbergs, University of Latvia.
The article (in three pieces of manuscripts), written in Russian, contains some reflections on graph theory. It may be written in 1973.
The graph on page 30 built from Petersen's graph is the flower snark J5, see http://en.wikipedia.org/wiki/Flower_snark. E. Grinbergs was building these graphs before 1975, when graphs named flower snarks were introduced by Rufus Isaacs.
