Extension 10:

a-(-)0,--b = a-(-)-(-) -(-) ... -(-) -(-) -(-) 0- - - ... - - -a with b (-)'s

a-(-)0,---b = a-(-)-(-) -(-) ... -(-) -(-) -(-) 0,--,- -,- -,- ...,- -,- -,- -a with b (-)'s

a-(-)0,0,--b = a-(-)0,-(-) 0,-(-) 0,... 0,-(-) 0,-(-) 0,-(-) 0- - - ... - - -a with b (-)'s

The limit of this extension is a-(-)0,0,0,...,0,0,1-b.
