I think there may be a typo in my organic chem book.  Is this a real structure?

(CH3)3C(CH2)3CH(CH3)2

Thanks for any help.  I did google this and I also asked a former chemistry teacher.

Its a funny way of writing it (twice falling victim to a version of the 'ole 1-alkyl alkane trick), but if you draw the structure out its legit. In this case the stage name is 1-tertbutyl-3-isopropylpropane, but the name on the birth certificate is it 2,2,6-trimethylheptane.
