| Summary: | The Kummer surface was constructed in 1864. It corresponds to the desingularization of the quotient of a 4-torus by 16 complex double points. Kummer surface is known to play a role in some models of quantum gravity. Following our recent model of the DNA genetic code based on the irreducible characters of the finite group <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mi>G</mi><mn>5</mn></msub><mo>:</mo><mo>=</mo><mrow><mo>(</mo><mn>240</mn><mo>,</mo><mn>105</mn><mo>)</mo></mrow><mo>≅</mo><msub><mi mathvariant="double-struck">Z</mi><mn>5</mn></msub><mo>⋊</mo><mn>2</mn><mi>O</mi></mrow></semantics></math></inline-formula> (with <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><mn>2</mn><mi>O</mi></mrow></semantics></math></inline-formula> the binary octahedral group), we now find that groups <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mi>G</mi><mn>6</mn></msub><mo>:</mo><mo>=</mo><mrow><mo>(</mo><mn>288</mn><mo>,</mo><mn>69</mn><mo>)</mo></mrow><mo>≅</mo><msub><mi mathvariant="double-struck">Z</mi><mn>6</mn></msub><mo>⋊</mo><mn>2</mn><mi>O</mi></mrow></semantics></math></inline-formula> and <inline-formula><math xmlns="http://www.w3.org/1998/Math/MathML" display="inline"><semantics><mrow><msub><mi>G</mi><mn>7</mn></msub><mo>:</mo><mo>=</mo><mrow><mo>(</mo><mn>336</mn><mo>,</mo><mn>118</mn><mo>)</mo></mrow><mo>≅</mo><msub><mi mathvariant="double-struck">Z</mi><mn>7</mn></msub><mo>⋊</mo><mn>2</mn><mi>O</mi></mrow></semantics></math></inline-formula> can be used as models of the symmetries in hexamer and heptamer proteins playing a vital role for some biological functions.

An analogy between quantum gravity and DNA/RNA packings is suggested.
