S6, with 720 elements, is the only finite symmetric group which has an outer automorphism. This automorphism allows us to construct a number of exceptional mathematical objects such as the S(5,6,12) Steiner system, the projective plane of order 4 and the Hoffman-Singleton graph. A closely related result is the following theorem: 6 is the only natural number n for which there is a construction of n isomorphic objects on an n-set A, invariant under all permutations of A, but not naturally in one-to-one correspondence with the elements of A. This can also be expressed category theoretically: consider the category whose objects are the n element sets and whose arrows are the bijections between the sets. This category has a non-trivial functor to itself only for n = 6.
Coloring isn't just for children ever again. It is also a great way to keep the kids busy and engaged, and provide some quiet time for everyone. There are distinct colors of life, of feeling and so forth.
Think before you decide on your colors. Your crayon colors are created from pigments. Coloring is important to the total development of a kid. You normally find the very same colors other men and women see. Sometimes it's better to go for the normal way of earning font colours and designs.
Doing a search on Google for printable coloring pages will bring up numerous different websites that offer you coloring pages to print. Google even offers a selection of pages with everything from dragons to princesses and Dora the Explorer to animals and sports cars. Each picture is accompanied with a link to the website it was taken from, so you get a huge range of websites you can look on to find different kinds of coloring pages. This is a wonderful resource that provides you with a diverse collection of free, printable coloring sheets. Individual character websites also often have great coloring pages to print. For example, by searching Google for the Strawberry Shortcake website, you can print a large number of high quality coloring sheets that will delight any little girl. You can try looking up other favorite characters for your child, such as Thomas the Tank Engine, Bob the Builder, and Curious George, and you’ll find some free coloring sheets you can print out at each site. It’s like having a hundred different coloring books at your disposal all the time.
A well-categorized coloring site is a great resource for teachers and parents, as well as for kids themselves. And the best sites have preformatted the pictures for easy printing. My favorite coloring site features two different kinds of coloring. First, there's the click-to-color pages, where very young children click on the color they want, then click on the part of the picture where they want to apply the color. This site features some 140 animals images that can be colored in this manner.
