The string __ will then be overwritten with additional \ and / where necesary.

There should be a few more rows of whitespace here, to make a total of 50, but I don't know if there is a way to format to include them.

The string " __ " will then be overwritten with additional \ and / where neccessary.

There should be a few more rows of whitespace at the top here, to make a total of 50, but I don't know if there is a way to get Stackexchange to format to include them.

creates an array of 50 strings of 50 spaces, then substitutes characters to add the hexagons:

 __ / \ \__/ 

As the first row contains spaces, once a hexagon has been plotted we cannot plot another one below it, because the spaces would overwrite the previous hexagons.

Therefore the hexagons are added in the form of a rhombus (distorted rectangle) from bottom to top, and slanting from bottom left to top right.

creates an array of 50 strings of 50 spaces, then substitutes 4 characters in 3 lines to add the hexagons:

" __ " "/ \" "\__/" 

As the first line contains spaces, once a hexagon has been plotted we cannot plot another one below it, because the spaces would overwrite the previous hexagons.

Therefore the hexagons are added in the form of a 16x16 rhombus (distorted rectangle) from bottom to top, and slanting from bottom left to top right.
