An octoquinquagintillion is equal to 10177 in America, or 10348 in France and Germany by Conway-Wechsler system.[1][2][3][4][5]
In the long scale which is commonly used in France and Germany, 10177 is called novemvigintilliard.
According to calculations by Ashton, it costs 4 octoquinquagintallion to buy a ticket to mars in the video game AdVenture Capitalist.
